TO ALL WHOM IT4 MAY CONCERN:

`Be it-known that I, LEWIS Gr. TUTTLE, ofthe town of North Haven, iu. the county of New Haven, and State of Connecticut, have iinvented a new and useful improvement in Cultivators g' and I do hereby declare that the following is a full, clear, and exact description of the construction, character, and opera-tion oi' the same,

4reference being had to the accompanying drawing, which maires part of this specification, which drawing is a perspective view of the cultivator, as taken from the near fore corner, showing the teeth or ploughs in theirV adjustable beams, the vertically adjustable shafts, and handles.

My improvement consists in making the cutterbeams .adjustable laterally to fit the rows, the shafts adjustable vertically to conform to the height of the horse, and the handles adjustable vertically to suit the height of the workman using it, I make the teeth or 'ploughs A A A A and Af of thin hollowed or curved steel or any other suitable material, and lit the front or centre tooth Avinto a suitable block attached to the front cross beam B, and each two of the four side teeth A A into each of the side horizontally adjustable beams C and D,

as shown in the drawing. lI make the two diagonal and adjustable beams C D of wood or any other-suitable material, and of suitable size, and I attach the front ends each to the, front cross-bar or beam B by m'eans' of bolts, one of which is shown at a, (while the other is concealed under H,) so 'that these beams maybe swung to be adjusted to the width of the rows, and be secured in their proper places by means of binding or thumbscrews,

(one of which is shown at 12,) which pass through holes c c and c in the cross-beam or bar E, and work in corresponding slots or mortises, as al, in the horizontal bar C, and a corresponding one in the bar I), which is not l seen. I maire the shafts G and Hof stitf-timber so that they will -not yield much in avertical direction; and

I attach their rear ends to the rear vends of the parallel bars I and K, by bolts or joint-pins, as shown'at e and e',

(which bolts also hold the Alower ends of the uprights 'R and S which support the handles.) And I adjust the shafts or thills to the height of the horse by suitable binding or thumb-screws, one of which is shown at g, which binding screws pass through corresponding holes as shown at t and L in the uprights L and M, and the shafts G and H, by means of which I can adjust the shafts to the height of any horse, so as to gauge the depth of the Vcut of the teeth, and I steady or support the shafts laterally by means of the cross-bar N. I make'the handles O and 'P of the ordinary shape, as shown, and attach their front ends to the parallel bars I and K by suitable bolts, one of which is shown at Z; and I adjust the rear ends to suit thc height of4 the workman by means of binding screws, as shown at m and m', which pass through corresponding holes in the uprights R and S, and the handles O and P, to render the cultivator more easy to be held or tended.

To use my cultivator, I place the horse between the shafts, and hitch the whiilie-tree to the hook IIL-adjust the beams C and D to the width of the rows, and the shafts to the height ot' the horse, as before described, so

that it will allow the teeth A A A A A to c ut to theproper width and the desired depth, and adjust the handles to Vsuit the workman, when he will be able to cut up or loosen the land between the rows to the desired depth, with the greatest certainty, ease, and convenience. i

What I claim as my invention, and desire to secure by Letters Iatent, is

The combination of the shafts Gr and H, when made vertically adjustable, with the beams C and D, when l made horizontally adjustable, and the whole is constructed and arranged substantially as herein described.
